Heat treatment of fresh turmeric rhizome
Fresh turmeric rhizomes were selected based on their
organoleptic properties and were cleaned before being
used for the heat treatment. The rhizome samples
(250 g · 3) were kept immersed in water in a plastic net
and maintained at 50, 60, 70, 80, 90 and 100 C for
30 min. After heat treatment, samples were cut into small
pieces and ground using a domestic mixer.
